Ertech is pleased to announce that we have been awarded a $128 million contract with to deliver the realignment and upgrade of a 2.4km section of the Great Western Highway including, a new interchange at Coxs River Road in Little Hartley, New South Wales.

The Coxs River Road project forms part of the $2.5 billion upgrade towards the East and West sections of the Great Western Highway Upgrade in New South Wales. The two-year project will be the first phase of work carried out in the Little Hartley to Lithgow section of the Great Western Highway upgrade between Katoomba and Lithgow.

The new interchange will include a bridge to travel over the new highway, and work will also include realigning parts of the existing highway to create a local service road, and upgrades to the intersections with Browns Gap Road and Baaners Lane.

The upgrades will reduce highway traffic through the historic township of Little Hartley.

The latest contract award builds on our growing track record in the road transport sector in the Eastern states of Australia.

Last week our Executive General Manager, Mick Unger, visited the project site with Shane Cahill, the Manager who will lead the project.  Mick commented “We consider Transport for New South Wales (TfNSW) a leader in sustainable procurement in Infrastructure and we value their forward-thinking approach from procurement through to project delivery.  Our team is delighted to be working with TfNSW on the Coxs River Road project.”

Ertech has commenced project start-up and will be mobilising to site shortly.  If you’re looking to get involved on an interesting project in a fantastic location, then we have a few opportunities on offer – Ertech Careers Page.
